T 0 all whom it may concern: 7 I

Be it known that I, EDW RD A. EVERETT, a citizen of the United States, and resident of in position and replaced, by one man; that i made to roll on one rail of the track, that is balanced on these rollers, that is rapidly brought into and taken out of the operating position, that grips-thelrail head and holds the drill in alignment and that automatically disengages itself from the rail when released.

- Other objects will appear from the follow ing specification and drawings in which,

. Fig. 1 is a sideelevation, partly in section, of

a track drilling machine embodying my invention Fig. 2 is a plan view, partly in section and with the engine removed, and Fig. 8 is a front'elevation showing certain details of the operating mechanism.

The gasolene engine 11 is adjustably secured to the pads 12 of the frame 14 by the legs 13. The frame 14 is mounted upon rollto fit the rail head-16 along which the machine is rolled.

29, Fig. 3, drives belt pulley 31. The roller 25, controlled by the handle 26, pivoted at 27, is provided for the purpose of tightening the belt and giving it the tension necessary for the different sizes of drills.

The spur wheel 33 is mounted on the shaft I means of an idler 33" running on bearing 34, spur wheel 35 is driven from spur wheel 33.

By a spline 37, wheel 35 drives the spindle 36 carrying the drill-38. This spindle runs in the ball bearings 39 and 40.

brought into use and quickly taken out of use latch handle 63 is raised releasing 'then handle 57 is. pulled out thus magazine 52 over until" the drill 38 engages v the rail; latchhandle 63 is now released, the feed is regulated by handle 62 and handle 57 as benecessary 'on the approach of a tra n. I therefore, provide a quick action I mechanism for this, purpose with a slow 123 Llberty St, New York, in the county of feeding'mechanism having considerable leverage.

j The drill is fedto the operating position by movlng the magazine 52 through the sleeve 51 by means of rack 53 engaged by the gear 54. This gear is rotated by the handle 62 havi'ngthe pivot 54 corresponding to thepi-vot of the wheel 54. Latch 64 locks the handle rigid with this gear; this latch is heldfin' engagement by the spring 65 and is released by the latch handle 63.

. Thelquick action is secured by handle 57 'pivotedat 58 and terminating in jaw 59?,

which engages the p'in 59 secured to the magazine 52c In the operation of the machine, gear .54, moving is held in positionby pin59. When the drill ;is to be-released latch handle 63 is raised and spring 60 restores handle 57 against the stop 61 and restores the drill spindle to the position shown. This long slide of the drill adapts the machine to drills of various lengths; it enables the drill to clear the fish plate 18 and the bolt heads, ers 15, on the shafts 41 and have a contour- ,or to position the drill against these parts for drilling the fish plate. It will be noted T that handle v62 operating the feed always as- The shaft 19 mounted in the bearing 20 of sumes the same relative position under these varying conditions.

into the clamping" position by depressing 'pedal;81, through lever 82, secured to bracket 83 on shaft 85 Spring 86 holds these clamps normally awayv from the rail head so that the machineis free to move when pedal 81 is not depressed. The lever 82 may be placed on the other side of the machine; and' attached -to bracket 84. Also secured to shaft 85. It will be noted from 1 It is an essential feature of a drilling ma chine of this type that it can be quickly Fig. 2 that the screw 89 is positioned between members 88 and 89, this three position grip of the rail holds the drill in alignchine for railway track resting apes the juste'cl to aligngthe drill at rig g the rail. For this urpose the hand e73 is.

ment by three point support which places the drill at right angles to the rail, and is a matter of importance in a power olierated drill. By clamping the rail head from the side toward the drill, the mechanism turnsupon the point of screw 89 as a pivot, enabling the drill to be brought mto the drilling-position with less clamping efiort than if the clamp were applied at the diseases side.

and the position of the res raised, unlatching Q until thefoot is positioned, when it is latched again, This enables the foot tob'e moved out otare vway of the ties when are madame is rolled alon the, track.

The engine is protected by the pipe railing 90 which also servesas a were or moving the machine along the or removing it from the track.- "eXtension 91 of this railingiormsa rest for the iii-amine when a is as are track. a

An oiling system is provided as is s s tial for the lubricationqo'f a high speed rill. This is conveniently located on the failing of the engine so that the operator oil the hole that is being drilled while standing erect and while manipulating the eperaaa mechanism of the machine. This consists of an oil tank 95 clamped to the pipe frame as shown and having a discharge pipe 97 terminating a noz'zle 98. When the plunger 96 is operated, the Gil in the is forced, under pressure, through the discl'iaifge pipe and into the hole that seei g drilled in the rail as indicated in Fig, 1.

Having thus described my invention, I claim;

1. A comparatively heavy drilling ma track rails, a drilling mechanism incorporated in said machine e eratifig a drill spindle, a handle for sliding said drill spindle into position against the rail to be drilled and an independent handle fdif' feeding said drill when drillingsaid rail, fiid feeding, and sliding handles being operative without changing the position ofsaid drilL ing machine relative to said rail.
